IMPROVEMENT IN MILL-BUSHES AND OTHER SPINDLES.

The Schedule referred to in these Letters Patent and making part of the same. i

To whom it may concern:

Be it known that .1, CHARLES '1. -WEsToN, of Scranton, inthe county of Luzerne and State of Pennsylvania, have inventeda new and useful Improvement in Mill-Bushes and their Spindles, applicable also to other purposes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawingforming part of this specification, and which represents a sectional elevation o'f a mill-spindle bush in its. place, with spindle applied thereto, the whole beingsconstructed in accordance with the invention.

My invention,'alth'ough applicable to verticaL revolvingspindles of fvarious kinds, is' mainly designed, and here will only be described. in such relation, to be applied to the spindles of grinding-mills, hullers, and other like machines in which horizontal stones or,tl1eir equivalents are used, and'the spindle is made to opierate the upper stone by means of a driver.

My invention consists in combining with the hush,- which' is arranged to project through the eye of the lower stone, an upwardly-extending sleeve to contain oil to lubricate said bush, and at the same time to protect the latter from dust.

I Referringto the accompanying drawing- A represents the vertical mill-spindle, working in' astep below and through a bush, B, above, i

This bush, instead of being immovably secured to the frame of the mill, is made capable of adjusting itself into parallel positions with the spindle during all oscillationsor deviations from truth of the latter, y

it with a by constructing said bush, or surrounding globe-joint, of which I) is the ball, and

-c o the socket, the-latter being made in. plates, 0 O, which may be adjustable by bolts d d relatively to each other, and the lower oneof which is secured to or rests on the frame of the mill.

The bush B projects,.as usual, through thelower stone, and is formed with a sleeve extending. up into the eye of the upper one, for reception of cotton-Waste or other fibrous material, to hold the lubricating ma terial supplied to it from above. I To feed in the oil without stopping the mill, or, of necessity, removing any of its working parts, the up-. per portion of the spindle A has a passage, e, made down it from the center at its top, and terminating in the side of the spindle belowthe upper edge of the bush B. I

Connected with this passagedown and through the spindle is an upper supply-tube, f, which may be mounted with an oil-cup'or reservoir, to keep the spindie and bush supplied, in an automatic manner, with lubricating matciial, the revolving motion of the spindle, or heat generated thereby, causing Lheoil to run or be drawn down the spindle as required. I

\Vhat is here claimed, and desired to be secured by Letters Patent, is

The upwardly-ex tending sleeve formed on the hush B, and surrounding the spindle Ato near the point of attachment 0? the driver, forming an annular space around the spindle to be supplied with oil, and to exclude dust from the hush, as shown and described.
